# Selin vs Period Tracker

The clearest difference is rating: Selin at 4.3 against Period Tracker's 1.0. Selin also leads on update cadence (weekly vs every 7 months) and ratings volume (10 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Selin sells 2 in-app purchases, starting at $7.99 per month and Period Tracker sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Selin holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: Selin has 10 ratings behind it against 1, so its average is the more settled of the two.

Selin ships an update weekly, Period Tracker every 7 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
